23 years ago today - Wednesday August 1st 1990 - Madonna's Blond Ambition tour was nearing the end and her final Spanish show - at the huge Olympic Stadium in Barcelona, took place.

This was the 2nd show of the world tour to be televised, with broadcasts of the Barcelona concert taking place that evening in the UK, Italy, Spain and elsewhere. Australian TV would air the concert a week later and in the coming months edited versions of the show were also broadcast in various territories.

Here's some very rare TV footage not intended for broadcast. Recorded from a live satellite feed, cameras show the Barcelona stage from various angles as the Olympic Stadium is filling up with fans a few hours before showtime!
